DESCRIPTION
The X88C64 is an 8K x 8 E
2
PROM fabricated with
advanced CMOS Textured Poly Floating Gate Tech-
nology. The X88C64 features a Multiplexed Address
and Data bus allowing a direct interface to a variety of
popular single-chip microcontrollers operating in ex-
panded multiplexed mode without the need for addi-
tional interface circuitry.
The X88C64 is internally configured as two indepen-
dent 4K x 8 memory arrays. This feature provides the
ability to perform nonvolatile memory updates in one
array and continue operation out of code stored in the
other array; effectively eliminating the need for an
auxiliary memory device for code storage.
To write to the X88C64, a three-byte command
sequence must precede the byte(s) being written. The
X88C64 also provides a second generation software
data protection scheme called Block Protect. Block
Protect can provide write lockout of the entire device
or selected 1K blocks. There are eight 1K x 8 blocks
that can be write protected individually in any combi-
nation required by the user. Block Protect, in addition
to Write Control input, allows the different segments
of the memory to have varying degrees of alterability
in normal system operation.
